Abstract (en)
[origin: US2002028916A1] There is disclosed a process for purifying a natural product using a two-phase, multi-solvent system followed by vacuum concentration and back extraction. The method allows for the removal of impurities by controlling the polarity balance of a two-phase system by manipulating the proportions of the four solvents and subsequently the relative distribution of the product versus the impurities.
